Griffiths

Who wouldn't want to tell Rachel Griffiths their deepest secret? Considering her heart-raw turns in Six Feet Under and the modern classic Muriel's Wedding, this warm, funny Aussie has a direct line to Empathy Central. Griffiths, 38, also costarred in My Best Friend's Wedding, and she's earning more BGF stripes as Sarah, the cool sister on the gay-happy prime-time soap Brothers & Sisters.
